Revision: da62cad10eda55aa233ac124273f3db4f541137a
Parent:   65bcb8cf8b32f68a5b48629b328f6d65979e58df
Author:   Thomas Moschny <thomas.moschny@gmx.de>

Branch:   net.venge.monotone

Changelog: 

* src/rcs_file.cc: Rename struct "file_handle" to "rcs_file_handle"
  to avoid a name clash with a struct of same name defined by newer
  glibc's "fcntl.h". For aesthetic reasons, also rename struct
  "file_source".
